this one was so frustrating because I did manage to work my way back to getting 911 as an answer for this but i had no idea how to put it in... inequalities are so hard and my head already hurts from doing them for like. 2 hours

some notes i took on one of the problems of solving for proportions w/ fractions. I got it wrong a few times before I realized I'd forgotten to flip. Eventually figured that out, and did n/8*5/11 = 5n/88
Now for 5n/88, how do you determine n?
5*n = 88 = TRUE
88/n = 5 = TRUE
88/5 = n = TRUE
The correct answer for finding the value of "n", is 88/5.
I still have to work a lot on this, fractions are one of my weakest points in math. But I was able to solve a few of the questions even though I didn't actually understand how, and I'm starting to at least be able to find where I'm making mistakes. I have hope!

fractions remain my achilles heel and solving these for unknowns is SO hard for no damn reason. hoping i can parse through the logic if i just keep working at it...
(first 2 are screenshots of a solution to a problem on Khan Academy, 2nd is a screenshot of a comment under a video From Khan A. about solving proportions w/ fractions)
